That's interesting about the fire hydrant. I find it hard to tell the difference, because the big joke here is that the UK doesn't even have fire hydrants as street furniture - we have signs to it, but actual access to the water main is under a flat metal plate built into the pavement - so hydrants all kind of look the same to me (and have a definite 'American' vibe). Completely out of place here!

I wasn't sure what that blob was meant to be - it looked a bit like another hydrant, so I got rid of it, but that's interesting if it's a post box. Definitely not a pillar box. :D
